SPECTACLE-TEMPLE AND MODE OF MAKING THE SAME.

' SPECIFICATION forming part of Letters Patent No. 440,220, dated November 11, 1890.

Application filed February 2'7, 1890. Serial No. 3%,022. (No model.)

To all whom it may concern:

Be it known that we, FERDINAND BUCHHOP and ALFRED J. ALLIBONE, citizens of the United States, and residents of New York, in the State of New York, have jointly invented a new and useful Improvement in Spectacle Temples and the Process of Making the Same, of which the following is a specification.

This invention consists, primarily, in hooktemples of novel construction, the hook portion of each being composed of two or more intertwisted strands so as to render it very strong and resilient, and having at the same time a practically unbroken cylindrical exterior whereby it is rendered smooth and corn fort-able to the wearer, while the diameter of the relatively stiff straight portion or main portion of the temple is merged into that of the hook portion so as to avoid any unsightly and uncomfortable shoulder or enlargement where the two unite.

The invention further consists in the peculiar process whereby such hook-temples are produced and certain novel features thereof, as hereinafter set forth and claimed.

A sheet of drawings bearing eight figures accompanies this specification as part thereof.

Figurel of the drawings is a side view of a finished hook-temple, illustrating this invention. Figs. 2, 3, 4, 5, and 6 are side views, more or less shortened by breaks, illustrating the process of manufacture; and Figs. 2 and and 3 are respectively cross-sections on the lines Ct at and b 1), Figs. 2 and 3, Figs. 1 and4 to 6 being drawn to one scale, Figs. 2 and 3 to a larger. scale, and Figs. 2 and 3 to a still larger scale.

Like letters of reference indicate corresponding parts of the product and blanks or stock in the several figures.

The finished temple, Fig. 1, is composed of, first, a straight or substantially straight and relatively stifi? main portion A, having conveniently the half-hinge hintegral therewith; second, a hook portion B, composed of intertwisted strands, but with a substantially unbroken cylindrical exterior, as represented in Fig. 3 and,third,atip O, preferablyrecurved, as shown, to keep said portion B from untwist ing and to fit comfortably behind the ear of the wearer, all said parts being inseparably united, and the diameter of said main portion A being tapered or merged into that of said hook portion B, so that there is no unsightly and uncomfortable break in the surface where the two adjoin. To produce such a temple, we proceed, as illustrated by Figs. 2 to 6, inclusive, as follows: The blank of the main portion A, roughly shaped, as shown in Fig. 4 only detached, is gotten out by swaging, with orwithoutthe aid ofdies,in customary manner. After, or in addition to getting out the blank of the main portion A, we twist together two or more, and preferably three, wires to to form the blank of the hook portion B, as illustrated by Figs. 2 and 2. We next draw said blank of the hook portion B through a draw-plate, which gives it its cylindrical and smooth exterior, and in a great measure prevents it from untwisting, as the original cylindrical form of the wires is thus destroyed. The product of this operation is represented by Figs. 3 and 3 The two blanks above described are next fastened together end to end by a rigid and secure joint j, which may be formed by hard soldering and compression, as illustrated by Fig. 4:. The partly-made temple is then trimmed, as illustrated by Fig. 5, the diameter of the main portion being merged into that of the hook portion, as aforesaid. The surplus metal may be removed in any approved way. It is now ready to re ceive the tip 0, which is securely fastened on the extremity of the hook portion, as by soldering. Finally, the hook portion is bent to the shape represented in Fig. l, or to any preferred shape. The temples may be made of any suitable metals or alloys, and when of steel may be tempered like ordinary steel temples. The temples may be sold in pairs detached, and may be hinged to frames of any approved construction in the production or alteration of spectacles.

Having thus described the said hook-temples and their manufacture, we claim as our invention and desire to patent under this specification- 1. A spectacle-temple comprising a relatively straight and stiff main portion, a flexible and resilient hook portion composed of intertwisted strands and having at the same time a substantially cylindrical and smooth exterior of a suitable diameter into which the diameter of said main portion is merged, and a terminal tip embracing the outer extremity of said hook portion and fast thereon, substantially as hereinbefore specified.

2. The withindescribed process of making hook-temples, consisting of intertwisting strands of wire to form the hook portion, then drawing the same to render its exterior substantially unbroken and smooth, then fastening' the same endwise to the main portion, then trimming both portions, then attaching a terminal tip to secure the strand ends of the hook portion, and finally bending the hook portion to the desired shape, substantially as hereinbefore specified.

3. In the manufacture of hook-temples, the processof forming a strong, flexible, and resilient hook portion having a smooth eXte-' FERDINAND BUOHHO'P. ALFRED J. ALLIBONE.
